When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

The aim of this study was to analyze discursive patterns in publications and attitude researches on bullying published by The Swedish National Agency for Education. The focus was largely on whether there is a pattern in the narration of how teachers and pupils are portrayed as perpetrators in a situation where bullying occurs. The empirical material of the study was acquired by use of a qualitative method where publications published between the years of 2002 and 2014 were selected. Dictums concerning teachers and pupils as bullies have been compared and surveyed where differences in how they were depicted was the object of analysis. To enable such a study, Foucault's theories on discourse and power were applied on the empirical material in the analysis.The result shows that bullying in general almost always refers to the pupil as the perpetrator while teachers are under-represented in the same context.

In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

The purpose of this thesis is to investigate how a public library, as an information center and a meeting place, may contribute to bring Swedes and immigrants closer to one another, which is a prerequisite for integration. To realize this purpose, I have asked three questions. Which conditions and demands are stated in central documents for libraries immigrant activities? What do the library called Biblioteket Västers multicultural activities contain? How does the library conceive its object to strengthen immigrants identity so that its activities, contribute to integration? As method, I have used hermeneutics, which means that I have interpreted the thesis material. In the theory I have described relevant literature and confirmed the importance of identity, language and the majoritys acknowledgement for integration.

The use of ERP in organisations is very popular and many companies have embraced this paradigm without really questioning why. Problems therefore often arise and cause high costs which is a result of poor planning. The paradigm also has its origin in the traditional architectural design that creates a system that has difficulties to adapt to organizations that are constantly evolving. The purpose of this study is to provide a different view of how IT-systems can operate within an organization and show how standard systems can be structured. We emanated from a case study at Linköping University Library, where we studied the implementation and integration of a standard system called Symphony.

We would like to learn more about how the restrictive policy against incentive programmes affects the board?s of Swedish state owned commercial firms ability to govern management in an efficient way. We also want to find out if there are different consequences in reference to this that are not directly linked to corporate governance issues. Our empiric observations have been made in order to profoundly explore the subject and examine it through the eyes of professional individuals, all expressing different views and standpoints. We conclude that the most efficient structure is when an active board is complemented by a well structured and individualised incentive programme.

Religious phenomena, such as prayer, have more or less always interested and engaged people, but most likely for different purposes. Since the early 20th century, starting notably with Edmund Husserl and especially Martin Heidegger, phenomenologists have taken an interest in understanding and expounding the meaning of religious phenomena. The attention of such a discourse have not ceased but is rather current, and also of importance seeing that religious themes, such as prayer, still occupy a great extent of human life and practice.Phenomenology of religion is not a science of religion: the former approaches religion in terms of its meaningfulness, whereas the latter as an object of inquiry and in the same manner as an economist approaches economical indicators in order to understand and explain how the whole economy functions. In other words, phenomenology of religion expounds religion, as it were, from within, while science of religion does it from without or externally.When approaching prayer phenomenologically, it shows itself to be a process or structure through which the one praying empty himself in order to be able to receive the valuable presence of the other. The value that is received from the other will also be reflected by the one praying and in that sense effect his surroundings and fellow humans..

The purpose of this study was to describe experiences in daily social life of parents of children with psychotic illness. Five parents with long-term experience of psychotic illness have been interviewed. The frame of reference in emotion theories of Thomas Scheff and Randall Collins have been used to analyze the results. The study is qualitative and has a phenomenological approach to shed lights of meanings in daily social life. The following meanings was found: Openness with certain reservation shows that honesty is important for the feeling of solidarity, Social expectations in daily life describes the parents´own expectations as well as expectations from others.

The object of this study is the female user of amphetamines and the characteristica which she is often described by. Many of these descriptions regard the female amphetamine user's sexuality which also have come to form the assumption that these women make a living from having sexual relations with men in exchange of drugs.In order to be able to draw any kind of conclusions regarding this, we found it necessary to investigate how the stereotypical female user of amphetamines makes a living and also whether it is possible for a female drug user to decide for her self how to support her habit.The disposition is a qualitative study of literature and the perspectives that we focused on in this study are gender roles, relationships and sexuality, criminality and finally the drug using woman as a victim. The theories used deal with social constructivism, respectability and shame.The main discussion of our study has been how women amphetamine users are moulded to become victims through interaction with other people but also with the society as a whole..

This thesis was created in an attempt to examine the concept of cultural heritage. What is cultural heritage to us and why do we treat it in the different ways we do? In my attempt to find an answer to this I have chosen to concentrate my interest on a situation where historical objects have been preserved as well as destroyed, Iraq 2003 until 2007. In my research I have divided the Iraqi cultural heritage in three different groups based on the different treatments they where exposed to during the occupation of Bagdad and the aftermath. For each group I have chosen one object or a category of objects to be a representative examined.

When contemplating entering an alliance the rationale behind the decision should differdepending on the size of the companies involved as well as on other important factors. The importantfactors influencing the decision are related to the resource pooling potential of the alliance,the power structure along with the business network the companies are a part of. Theanalysis has shown proof of a need for cooperation if one wish to succeed in the telecommunicationindustry and it has also determined which resources that are deemed to be most important toget in touch with, for our study object, to facilitate its access to the market. Those resources aredefined as a direct channel to the customer, funds/capital and the access to relevant businessnetworks. To get in touch with these lacking resources, three alternative approaches has beenproposed; all of them involving a strategic alliance decision.

The Swedish Armed Force has a need to streamline the preparation of an exercise in tactical training for soldiers because the preparation of an exercise is currently laborious and time consuming when commanders manually share files to each computer that will be included in the exercise. The degree project was to create a file sharing program within the internal network of the Defence Forces? international centre (Swedint). The program is used by the training management to effectively start up an exercise where soldiers train tactical training in a simulated combat environment. The training management use this program to upload files to a server which notifies all the computers on the network to download these files.

This study analyses the german writer and artist Unica Zürn´s novel, The Man of Jasmine,1970 (Jasminmannen). Zürn was mostly active in the surrealist avantgarde in Paris during the 1950ies - and 60ies. The male surrealist images of women was polarised in to the godlike, child and the erotic, convulsive object. The mythologizied woman was the muse of men´s creativity. But still there were many women artists who participated in the movement, so clearly there was something in surrealism that attracted women.

My goal with this Project was to create four pictures which de¬scribed four different emotions. The purpose of the project was that the pictures would be placed in a psychology department and they could use them as a starting point for a discussion about the patients? emotions. My personal purpose was that I wanted to create pictures in scale 1:1 in an analogue fashion, and try to learn more about how people see and feel about pictures. What kind of thoughts can a picture give you? Can I create a picture which can be used as a platform for a discussion? Can I make a picture which describes an emotion? The making of the pictures started with developing ideas and then I took photographs of my friend Joel, in different situations and moods, which I used as reference for my paintings.
